This invention relates to a container for dispensing pasty substances and more particularly to such a container-having an interchangeable inner container.

One objectof my invention is to provide a container for a. creamy or pasty substance, which is to be discharged from time to time in small amounts in relation to the total content of the container, the amount discharged being accurately controlled and measured.

Another object of my invention is toprovide a dispensing container of simple construction which can be operated with only one hand;

A further object is to provide a dispensing'con tainer having a maximum useful content for the pasty substance being dispensed.

Stillv another object is' to provide a containerfor pasty substances which is so constructed that a replaceable inner container can be inserted therein, without requiring alignment of the inner container while it is being insertedand the contents. of the inner container can then be discharged.

- Alstill further object of my invention isto provide a dispensing container in which a paste is caused to be: emitted from a'replace'able. inner container through means resiliently coupled toengage the bottom of the inner container of'the cream'box of thisinvention.

Like reference characters refer to like parts throughout the several figures of the drawing. In Figure 1 or'the drawing, the numeral I designates the outer casing of a container having a. bottom part 2, which may be either integral with or attached to the casing l. A cover 3, of approximately'the same diameter as the outer casing I, is adapted to fit against the upper surface of the casing. A cylindrical lining or housing 4 is designed to fit inside the casing I with enough. clearance. to permit relative rotation of the. housing, and the casing. At its lower end,

6 Claims. (01. 222 -327) the housing 4 is turned inwardly to iorm a flange I A disk 6 issecured to the upper surface of the bottom 2*of the container by welding, soldering, or other-"suitable means. The disk 6 is'provided with a peripheral're'cess into which the flange 5 ofthe'liousing 4 fits. The disk 6 prevents longitudinalmovementOfthe flange 5 and the housing 4, but permits rotation of the flange and the housing with respect to the disk 6. To the upper surface of the disk 6 is secured by Welding, soldering, or other suitable means, a coil spring T'of fiat cross section. The turns of the coil sprin 1 have considerably greater width in a radial direction than thicknessin an axial direction and the'sprin'g 'niay be formed from sheet metal. Accordingly, when fully compressed, the spring: I occupies a minimum of space. Moreover, by providing a spring of flat cross section, distortion of the-spring when transmitting torque is substantiallyeliminated. To the upper end of the spring I is secured by weldingsoldering, or

other suitable meansadisk 8, having'in its upper surface a nonround recess 9. -The recess 9 may be rectangular, star-shaped or of any other suitable nonround shape.

replaceable inner container is sodiniensioned ast'o fit-snugly inside the housing 4. The inner container has acylindrical side wall It Which-is threaded internally throughout its entire length. A top H of substantially circular shape has a flange l2 fitting into a peripheral recess at the a portion of the top upwardly into-a circular" flange. The opening l3 registers with the corres'pon'ding opening in the cover 3-o'f the outer casing and a dish-shaped protuberance or deposit surface M: is formed about this'latter opening. A {cap I'd-is proyided' to fit over the protuberancel i.

The 'bottom of the inner container is formed by a diskor piston I 6, which is in screw-threaded engagement with the cylindrical Wall IQ of the innercontain'er. To the lower surface of the disk I6 is secured'by'welding, soldering, or other suitable means, a smaller disk IT.

of steel 'and is substantially annular in shape. ,At oneend, the wire '18 is bentto forma pro- The disk ll'is 0f a: suitable nonround shape to fit within and to 3 Jecting pin or stud l9 which extends into a notch or recess 20 in the housing 4. The opposite end of the wire I8 is bent to form another pin or stud 2| which extends into a recess or notch 22 in the bottom of the side wall I of the inner container. In the case of the wire I8 illustrated in Figure 1, it will be seen that the wire is in a wavy shape. In the case of the modified form of wire 28 illustrated in Figures 3 and 4, it will be seen that the wire is substantially fiat, but is bent upwardly, as at 23, in order to elevate the the outer casing, its disk or piston l6 contacting the disk 8, as the inner container is pushed inwardly, and compressing the coil spring I. When the new inner container is inplace, the cover 3 is fitted over the top H of the inner ,contsiner and about the housing 4 until the cover comes into contact with the upper surface of the outer casing. The cover 3 is dimensioned so as to fit tightly, about the housing 4 and the side wall H] of the inner container so as to transmit by friction rotation of the cover 3 to the side wall H]. In assembling a new inner container, it is not necessary to align the parts. -This is done by rotating the cover 3 and thereby the side wall Ill of the inner container relative to the outer casing l, which is connected through the. bottom 2, disk 6 and coil spring I to the diskB. By such rotation,'a suitable amount, the disk I! willcome into alignment with the -recess9=in the disk 8 and likewise the pin or stud 2| on the wire l8 or 28 will come into alignment with andrwill snap into the recess or notch 22 in the bottom edge of the side wall I 0. The pin or stud 9 on the other end of thewire |8 remains incontact with the recess or notch 20in the housing 4 while inner containers are being changed.

After the parts have been assembled, as described above, measured emission of the paste contained in the inner container will be effected by holding the outer casing in the palm of one hand and rotating the cover 3 with the thumb and forefinger of the same hand. As has been explained, the cover 3 is keyed by friction to the side wall l0 in the inner container and the outer casing is attached to the disk 8, which through the recess 9 and cooperating disk becomes keyed to the disk or piston I6. Accordingly, when the cover 3 is rotated relative to the outer casing-l, the disk or pistonlfi is rotated relative to the side wall H! of the inner container and axial movement of the disk or piston I6 is thereby eifecteda This causes emission of the paste through the discharge opening l3 and, it will be appreciated, due to the relatively rigid connection of the parts, the amount of paste emitted can be accurately controlled. Should an excess of paste be emitted, it can be retracted byreversing the direction of relative rotation of the parts.

It will be appreciated that there is provided by my invention a container for dispensing pasty substances in which a replaceable inner container of maximum size may be used. This is so because of my use of a coil spring of flat cross section to transmit rotational torque. The coil spring, being preferably made of fiat sheet metal, has considerably more radial width than axial thickness and accordingly occupies a minimum of axial space in the outer casing when it is fully compressed, which is when the replaceable inner container is full.

Another advantage of using a spring of fiat cross section to transmit torque is that such a spring transmits the torque with a minimum of distortion, whereas a spring of round cross section readily becomes twisted out of shape.

Another advantage of the container of my invention is that it is so designed as to be operable by only one hand. Accordingly, it is very convenient in use.

The container of my invention makes possible the ready use of replaceable inner containers. In removing empty inner containers and inserting full inner containers, it is not necessary to align the new inner container with the outer casing, since the connecting parts will automatically become keyed together by rotation of the cover 3 relative to the outer casing I. Thus, the replacement of inner containers can be effected with great facility.
